Abstract: Methods for preparing oxidizing agents having enhanced water solubility properties, such as magnesium permanganate, calcium permanganate and ammonium peroxydisulfate are prepared from oxidizing agents having more limited water solubility properties, such as potassium permanganate and potassium peroxydisulfate by electrochemical means employing oxidant stable, cationic permselective ion-exchange membranes that are also suitable for transporting a preponderance of cations with lower water of hydration, such as potassium over other more highly hydrated cations, such as sodium, magnesium and calcium used to replace the leaving potassium ion, and form more soluble oxidizer salt solutions. The methods may be practiced in multi-compartmentalized electrolytic cells, such as metathesis electrodialysis cells.

Abstract: Novel electrochemical cell configurations comprise ion-exchange membranes in combination with at least one porous separator for use in salt splitting methods, including metathesis electrodialysis salt splitting. Methods include production of chemically different oxidizing agents from a first oxidizing agent feed, along with value added salt by-products without adversely affecting permselectivity of the ion-exchange membranes of the cell.

Abstract: A method of producing potassium permanganate in an electrolytic cell is described where the cell is separated into a catholyte and anolyte region, potassium hydroxide is made in the catholyte region and is recycled back into upstream portions of the process to oxidize permanganate dioxide bearing ore.
